Searching the World Wide Web for Local Services and Facilities: A Review on the Patterns of Location a service name accompanied by a location name. Our survey indicates that at least 22% of the Web queries have a geospatial dimension and most of these can be considered as location-based queries. We propose that location-based queries should be treated different from general queries to produce more relevant results.

Self-adaptive Statistics Management for Efficient Query Processingement where, using query feedback information, an appropriate set of histograms is recommended and refined, and through histogram refining and reconstruction, fixed amount of memory is dynamically distributed to histograms which are most useful to the current workload. Extensive experiments showed the effectiveness of our techniques.

Construction de Series Discretes p-adiquesver physically modify original data, rather creates new version for compensating data intactness. Due to data intactness, search operation can access data without any locking or latching by reading old version. In the performance evaluation, it is proven that search operation of R.-tree is at least two times faster than a previous work.

Lecture Notes in Civil Engineeringerent cost factors are attached on the training errors to generate an optimized hyperplane. Our experiments show that CS-SVM outperforms SVM on the standard ODP data set. The web pages with relative high PageRank values contribute most to the classifier and using them for training can exceed the random sampling technique.

Risk Assessment in Construction Businessessmall. Such feature makes it very efficient for interactive mining. The algorithm we proposed has been implemented and its performance is compared with re-running Eclat, a vertical mining algorithm, under different minsup. Experimental results show that our algorithm is over two orders of magnitude faster than the latter in average.

Modifications of the Counting Scheme, SOAM is given to acquire OWL ontology automatically as much as possible. Different from existing methods, the implementation method not only can acquire OWL ontology from relational database directly without demanding a middle model, but also can refine obtained ontology according to existing lexical knowledge repositories semi-automatically.
